"One of the best!"

The TF1 Omega Filter is one of the best filters made.

"Fast warm up, all radiators even heat, no trapped air"

Fernox gives real confidence. It does all expected. Always used Fernox products, recently needed to drain partially to fit a new valve. No evidence of sediment. I topped up with the F1 and several weeks later the heating is working perfectly. Fast warm up, all radiators even heat, no trapped air.
